    • A process for producing an electrode for electric discharge surface treatment capable of forming of a coating excelling in abrasion resistance over a temperature range from low to high temperature by electric discharge surface treatment; and such an electrode for electric discharge surface treatment. There is provided a process for producing an electrode for electric discharge surface treatment useful in electric discharge surface treatment in which using as an electrode a molded powder obtained by molding of a metal powder, or powder of metal compound, or powder of conductive ceramic, pulsed electric discharge is generated between the electrode and a work in a machining liquid or gas so that by the energy thereof, on the surface of the work there is formed either a coating consisting of the material of the electrode or a coating of substance resulting from reaction of the material of the electrode by the pulsed electric discharge energy, which process comprises increasing the oxygen within the powder; mixing together the powder with the oxygen increased, an organic binder and a solvent to thereby obtain a mixture liquid; carrying out granulation from the mixture liquid to thereby obtain granulated powder; and molding the granulated powder to thereby obtain a molded item of 4 to16 wt.% oxygen concentration. ® KIPO & WIPO 2009

    • The twin roll casting machine comprises cooling rolls (1), side weir (2) and molten metal supply nozzle (4) and further comprises baffle (11) connected to an inferior portion of end face of the molten metal supply nozzle (4), the baffle (11) projecting toward the side weir (2) in molten metal reservoir (8), so that the flow (S) of the molten metal toward roll gap (G) is blocked by the baffle (11). Accordingly, any hot molten metal just after being poured would not move along the side weir (2) to immediately reach the roll gap (G), and instead the molten metal cooled by a lapse of time after being poured would accompany the rotation of the cooling rolls (1) to thereby intrude in the roll gap (G). Therefore, any delay of solidified shell generation in the vicinity of an edge portion of the outer circumferential surface of the cooling rolls (1) would be resolved, and strip (3) delivered from the roll gap (G) would not suffer any reduction of the thickness thereof at edge portions in the direction of the width, so that strip (3) having a uniform thickness over the whole width can be obtained.
    • 双辊铸造机包括冷却辊(1),侧堰(2)和熔融金属供给喷嘴(4),并且还包括连接到熔融金属供给喷嘴(4)的端面的下部的挡板(11) 所述挡板(11)在熔融金属容器(8)中朝向侧堰(2)突出,使得熔融金属朝向辊间隙(G)的流动(S)被挡板(11)阻挡。 因此,刚刚浇注后的任何热熔融金属都不会沿侧面堰(2)移动,以便立即到达轧辊间隙(G),而是在浇注之后经过一段时间冷却的熔融金属将伴随着 冷却辊(1),从而侵入轧辊间隙(G)。 因此,冷却辊(1)的外周面的边缘部附近的凝固壳产生的延迟将被解决,并且从辊间隙(G)输送的带材(3)不会受到任何减少 其在宽度方向上的边缘部分处的厚度,使得可以获得在整个宽度上具有均匀厚度的条带(3)。
